However, the technical solutions disclosed in these utility model patents focus on the ease and quick fixation at designated locations, good stability, and ensuring the positional accuracy of test data. They do not further address the practical needs of simultaneously monitoring multi-directional and unidirectional noise in hydropower units, and therefore require further improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a sensor arrangement structure for monitoring noise in hydropower units.

The sensor panel is embedded in the machine panel and rotatably connected to the machine panel. The two sensor uprights are fixedly connected to the sensor panel. The three sensor rotating rods are parallel and equally spaced, and are rotatably connected to the sensor uprights. The middle sensor rotating rod is equipped with two noise monitoring sensors, and the two side sensor rotating rods are each equipped with a noise monitoring sensor.

Detailed Implementation

[0020] This utility model discloses a sensor arrangement structure for noise monitoring of a hydroelectric generator unit. The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0021] See attached diagram. Figures 1 to 8 , Figures 1 to 3 The arrangement of the hydropower unit noise monitoring sensors from different perspectives is shown. Figure 4 An assembly of multiple sensor modules is shown. Figures 5 to 7 The sensor modules are shown from different perspectives.

[0022] Example 1.

[0023] Preferably, the noise monitoring sensor arrangement structure for the hydropower unit includes a base 100, a platform 200, and multiple sensor modules 300, wherein: The machine base 200 is fixedly connected to the machine base 100, and the machine base 200 includes a machine base panel 210; The sensor module 300 includes a sensor panel 310, two sensor uprights 320, and three sensor rotating rods 330. The sensor panel 310 is embedded in the machine base panel 210 and rotatably connected to the machine base panel 210. The two sensor uprights 320 are fixedly connected to the lower surface of the sensor panel 310. The three sensor rotating rods 330 are parallel and equally spaced. The three sensor rotating rods 330 are rotatably connected to the sensor uprights 320. The middle sensor rotating rod 330 is equipped with two noise monitoring sensors 340, and the two side sensor rotating rods 330 are each equipped with one noise monitoring sensor 340. The noise monitoring sensors 340 are sleeved on the sensor rotating rods 330 and fixedly connected to them. This allows the noise monitoring sensors 340 to rotate synchronously with the rotation of the sensor rotating rods 330. Only a portion of the noise monitoring sensors 340 are always exposed on the outside of the sensor panel 310, while most of the noise monitoring sensors 340 are always hidden on the inside of the sensor panel 310.

[0024] As an explanation, on the one hand, the sensor panel 310 is rotatably connected to the machine base panel 210, allowing each sensor module 300 to rotate independently relative to the machine base panel 210; on the other hand, the sensor rotating rod 330 is rotatably connected to the sensor upright plate 320, and the noise monitoring sensor 340 is sleeved on and fixedly connected to the sensor rotating rod 330, allowing each noise monitoring sensor 340 of each sensor module 300 to rotate independently relative to the sensor upright plate 320; furthermore, only a portion of the noise monitoring sensors 340 are always exposed on the outside of the sensor panel 310, while most of the noise monitoring sensors 340 are always hidden on the inside of the sensor panel 310, allowing multiple noise monitoring sensors 340 to face noise sources in the same direction or in different directions, fully meeting the actual situation of simultaneous multi-directional and unidirectional noise in hydropower units.

[0025] The sensor plate 320 has three first positioning holes 321. One end of the sensor rotating rod 330 is connected to the first positioning hole 321 of the sensor plate 320 on one side, and the other end of the sensor rotating rod 330 is connected to the first positioning hole 321 of the sensor plate 320 on the other side. This allows the two ends of the sensor rotating rod 330 to be connected to a first driving mechanism (not shown in the figure), so that the first driving mechanism can drive the sensor rotating rod 330 to rotate, thereby driving the noise monitoring sensor 340 to rotate.

[0026] The sensor plate 320 also has a second positioning hole 322, which is spaced from the first positioning hole 321. A rotating rod (not shown in the figure) is inserted into the second positioning hole 322. The rotating rod is further connected to a second driving mechanism (not shown in the figure) so that the second driving mechanism can drive the rotating rod to rotate, thereby driving the sensor module 300 to rotate.

[0027] As an explanation, the first drive mechanism and the second drive mechanism are existing technologies, and they can be either independent drive mechanisms or the same drive mechanism.

[0028] The machine base 200 also includes a machine base plate 230 and four machine base upright plates 220. The four machine base upright plates 220 are fixedly connected to the machine base panel 210 and the four machine base upright plates 220 are fixedly connected to the machine base plate 230, so that the machine base panel 210, the machine base plate 230 and the four machine base upright plates 220 together form an inner cavity for accommodating multiple sensor modules 300.

[0029] The base 100 includes four support legs 110 and four foot pads 120. The four support legs 110 are fixedly connected to the base plate 230 of the machine platform, and the four support legs 110 are fixedly connected to the four foot pads 120.

[0030] It is worth mentioning that the specific structures and other technical features of the first and second drive mechanisms involved in this utility model patent application should be regarded as prior art. The specific structures, working principles, and possible control methods and spatial arrangements of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0031] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
